Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] see figure 1 and figure 2 The U-shaped assembled reinforced concrete cover culvert of the preferred embodiment of the present invention is surrounded by the prefabricated reinforced concrete cover, the prefabricated reinforced concrete side wall and the cast-in-place reinforced concrete bottom plate 3 from above, both sides and below around the axis of the culvert respectively. The prefabricated reinforced concrete side walls on both sides are symmetrical about the axis of the culvert. The prefabricated reinforced concrete cover slab comprises a plurality of prefabricated reinforced concrete cover slab segments 1 sequentially fitted along the axis of the culvert. The prefabricated reinforced concrete side wall on each side includes a plurality of prefabricated reinforced concrete side wall segments 2 sequentially fitted alon...

Abstract

The invention discloses a U-shaped assembly type reinforced concrete cover board culvert which is enclosed through a prefabricated reinforced concrete cover board, prefabricated reinforced concrete side walls and a cast-in-place reinforced concrete bottom board. Prefabricated reinforced concrete side wall sections are prefabricated into a whole through vertical wall sections, vertical wall toe board sections and vertical wall heel board sections. Multiple transversely-arranged connecting reinforcing steel bars are embedded in each vertical wall toe board section and each vertical wall heel board section. The connecting reinforcing steel bars extend outwards from the longitudinal end face of each vertical wall heel board section. Multiple reinforcing steel bars are arranged in the cast-in-place reinforced concrete bottom board, wherein the two ends of each reinforcing steel bar are welded to the corresponding connecting reinforcing steel bars on the two sides. The cast-in-place reinforced concrete bottom board is sequentially connected with the vertical wall heel board sections opposite on the two sides in the axial direction of the culvert. The invention further discloses a construction method of the U-shaped assembly type reinforced concrete cover board culvert. Prefabricated components are manufactured in a centralized manner and lifted and spliced on a field, the engineering quality can be effectively improved, the construction period is saved, and economic benefits are improved.

Description

technical field [0001] The invention relates to the field of culvert and channel structure engineering, in particular to a U-shaped assembled reinforced concrete cover culvert and a construction method thereof. Background technique [0002] At present, most of the existing slab culverts are constructed by pouring the vertical walls and foundations on site, and the centralized prefabrication of the cover slabs. [0003] The limitations of this kind of slab culvert are mainly reflected in two aspects: one is that the quality control of the on-site pouring project is difficult, and the required construction period is longer; the other is that the existing prefabricated slab culvert has a poor structure and a narrow scope of application , is not universal. [0004] Under the requirements of minimizing the impact on traffic in the process of new road construction or reconstruction, there are more and more demands for prefabricated culverts. Therefore, it is necessary to develop ...
